SPECIFICATION forming part of Letters Patent No'. 309,015, dated December 9, 188%.

(No model.)

To aZZ whom, it may concern.-

Be it known that I, HENRY E. WILLER, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of lVisconsin, have invented certain new and useful Improvements in Adjustable \Vindow- Screens; and I dohereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

,The object of my invention is to provide means by which that class of screens which are formed in two parts adj ustably connected together at their inner edges are adapted to be used both at the top and bottom of the window, either, upon the outside or inside of the sash, as desired.

The two frames of my screen are made and adjustablyconnected to each other substantially as shown in United States Patent No. 266,246, granted to me October 17, 1882, and my present improvements pertain more especially to the retaining ways in the window frame and those in the screen by which they are adapted to co-operate together and permit of the screen beingoperated in the several positions mentioned.

My improvements are further explained by reference to the accompanying drawings, in which- Figure 1 represents a perspective view of a window provided with my improvements. Figs. 2, 4, and 6 are vertical sections of a window, showing my screen in the several positions at which it is adapted to be adjusted. Figs. 3, 5, and 7 are horizontal sections of the respective views shown in Figs. 2, i, and 6.

Like parts are represented by the same reference-letters throughout the several views.

A represents the ordinary window-frame, provided with window-sash B and O. D is the outside and E the inside of the window.

My adjustable screens are formed in two parts, F and G, which are connected together at their contiguous edges by bolts H 11, provided with hand-nuts I I, said bolts being rigidly aftiXed at their rear ends to the rear or inner frame of the screen, while their front ends extend through slots J J, provided therefor in the front screen, said slots J J permit ting of the required adj nstment of said screens to conform to the various widths of window frames to which the screens may be attached, while said screens are rigidly secured to each other at the desired point of adjustment by turning down said hand-nuts I I.

It is obvious that when the two sections of the screen are thus secured together and attached to a window-frame, as shown in Fig. 1, a space is left between the front frame and the window-sash corresponding to the thickness of the rear screen-frame, to close which space the slat K is provided. The slat K is attached to the upper bar of the front frame, and extends rearward to the window-sash on a line with the rear surface of the rear frame, whereby the entire space between the front section of the screen and the sash is closed.

WVhen the screen is in the position shown in Fig. 1, as described, the lower window-sash is raised in front of the upper one, and the upper edge of the screen is closed against the lower rail of the lower sash. When, however, it is desired to lower both window-sashes anduse the screen at the top of the window, it becomes necessary to invert the screen, so that the slat K will be brought below to close the space as before between the front section of the screen and the top of the window.

It is obvious that when the screen is in the position shown in Fig. 7 the retaining-groove d in the front section engages in the front way or bead, while the groove (1 of the rear frame engages in the rear bead. Presuming, now, these screens to be inverted, it is obvious that the front screen will either be brought rearward or to the opposite side of the frame, and it therefore becomes necessary to provide the respective sides of the window-frame with two beads, a a, upon its respective sides, both of uniform construction and at uniform distances apart, whereby it is obvious that both sections will thereby be provided with ways on which to move both at the top and bottom, whether inverted or otherwise,with either surface outward.

To accommodate the space-closing slat K to the several positions of the screen, it also is provided with grooves or ways d, conforming to the shape of the retaining-beads a.

In case it is desired to use the screens upon either the inside or outside of the window two sets of ways are provided, as shown inFigs. 2 to 7 These ways may be permanently attached to the sides of the window-frames, and the screens attached to them or removed from one set of them to another simply by releasing the hand-nuts I and contracting the frames of the screens sufficiently to permit them to slip past and engage in said beads, when the sec tions are again slightly extended and the handnuts turned down, thus rigidly'locking said sections at such adjustment.

In Figs. 2 and 3 the screen is shown upon the outside of the window below the sash, the sash being closed, while in Figs. 4 and 5 the screen is shown upon the inside of the window, with both sashes raised. It is obvious from a comparison of Figs. 3 and 5 that in thus shifting the screen from the outside to the inside, or the reverse, it becomes necessary to turn the screens without inverting them so that their face side is in the opposite direction that the space-covering slat K may thereby be brought to close the space between the front screen and the window-sash both at M and N.

In Figs. 6 and 7-the screen is shown at the top of the window at the outside of the easing, lootli sashes being down.

In Fig. Gthe slat K is shown closing the space between the outside section of the screen and the upper rail of the upper sash, while in Fig. 7 the slat K is removed to show the space between said outer section of the screen and the sash-rail which said slat K is adapted to close. Thus it is obvious that by providing double ways extending from top to bottom on both sides of the window-frame, andalso providing the respective sections of the screen and the slat K with corresponding ways, I am enabled to use my screen at either thetop or bottom of the window; also, that by using double ways upon both the inside and outside of the frame I am enabled by reversing sides or by inverting said screens to change them from any one position to any of the others in the window, and still adjust them to closely fit the sash in all positions.

Having thus described my invention, what I claim as new, and desire to secure by Letters HENRY E. WILLER.
